Thanks for the info. But I solved the problem easier. Amplifier I turn on by the pedal with the foot, and the transceiver - with the tangent.

Hi Oleg, once I can get my hands on the schematics I will try to locate what you need. 73, KE5QLX

It took more than a year, the guarantee was over, and I decided to modify my radio. Set the relay to connect an external amplifier.

This requires two parts. Connector for connecting video - audio equipment with a thread diameter of 6 mm, and a small-sized relay for 9 volts. I used the Soviet relay (02.01), This is a very good relay, it was used in military and space technology in the USSR, the content of precious metals in relay РЭ49 РС4.569.421.00.01, РЭС49 РС4.569.421.01.01, РЭС49 РС4.569.421.02.01, РЭС49 РС4.569.421.05.01.

Gold: 0.000525 grams.
Silver: 0,02937 grams.

The connector for grounding should be removed, its diameter is exactly 6mm, I drilled it in a vice.

Now you need to remove the small connecting cables of reception and transmission, which connect the upper and lower modules. Be extremely careful! The earthing of the cables is soldered, it needs to be cleaned very neatly, and when assembled, soldered back. Do not damage them with a powerful hot soldering iron!

Carefully install the disassembled transceiver for further work. Take care not to damage the connecting lines of the processor and the display!

Now you need to find the point TP8B on the amplifier board. This is a voltage output of 9 volts for inclusion on the transmission.

Solder to this point a thin quality wire for the relay.

Install the relay. How I installed our Soviet relay, can be seen in the photographs. Probably you will use other relays, then the technical solution depends only on your imagination.

Now You can mount the transceiver in the reverse order.
DO NOT HURRY! ACCOUNTABILITY IS IMPORTANT!

We make grounding. I hope you do not need to explain how.
